The distance from Elena's chin to the top of her head is 150 mm in an imag
ollegr [7]

The height of the image of the ditance from Elena's chin to her head after it has been scaled 80% 3 times is 76.8 mm

<h3>What is the height of the image after it has been scaled?</h3>

When an image is scaled, it means that its dimensions have been reduced by a certain percentage. In this question, the image is reduced by 80%.

The height of the image after it has been scaled = 150 x 0.8^3 = 76.8 mm

The total of two numbers is 28. Four times the smaller number is 7 more than three times the larger number.
navik [9.2K]
Let's define:
x \ \textless \ y

So, you can set up a system of equations:
x + y = 28
4x = 7 + 3y

Now, to solve for both of those values, solve the system of equations:
x = 28 - y
4(28-y) = 7+3y
122-4y=7+3y
115 -4y = 3y
115 = 7y
y = 16.43

Now, plug that y-value into the first equation to solve for x:
x + 16.43=28
x = 11.57

Now, we have both the values. The smaller value (x) = 11.57 and the bigger value (y) = 16.43.

Rahul solved the equation 2(x – 1/8 ) – 3/5x = 55/4.
4vir4ik [10]

He used it in step 3. The Addition Property of Equality states that whatever you add to one side, you must add the same quantity to the other side. In this case, he added 1/4 to both sides.
